Discount codes not working anymore?

I`ve placed a few orders over the last 3 weeks or so and used discount codes that the page indicates were accepted(one was expired so I assume the other was good) but it is never applied when I pay.If it was a buck or 2 I wouldn`t care but the orders were roughly $200, $100 and $150. Is there an issue or did I do something wrong?

Which codes did you use?

Some of them will expire after a given amount on time as they're intended to.

Good idea to issue a working code but I already spent $450 without a working code. I`m not expecting anything back, I just would like one for the next round(Feb 1st?). Maybe an email with new codes as they are issued and an expiration date?
